fix(core): swc should be an optional peer dependency

[AgentEnder]

Current Behavior

A minimal install of nx includes @swc/core as well as @swc-node/register

Expected Behavior

• A minimal install of nx doesn't reference swc
• Attempting to use behavior that requires swc-node (e.g. workspace lint rules or local plugins) provide good feedback when the dependency is missing, and install it if possible.

Screenshots

Attempting to run a local plugin's generator that was created manually, in a @nrwl/js publishable lib
Note, pulling in @nrwl/js pulls in @nrwl/jest, which itself includes ts-node. This PR adds a fallback such that it was able to be used.

Attempting to run the same generator, with ts-node removed manually

Changes to package.json from running nx g @nrwl/nx-plugin:plugin
